The Trans-Global Highway is a proposed highway system that would link all continents of Earth except Australia and Antarctica. The highway would network new and existing bridges and tunnels, improving not only ground transportation but also potentially offering a conduit for utility pipelines. It was proposed by Frank X. Didik.
In 1890 William Gilpin first proposed to connect the continents by land via the Cosmopolitan Railway. Significant elements of that proposal, such as the English Channel Tunnel, have been constructed since that era. However, the improvement of the global shipping industry and advent of international air travel has reduced the demand for many intercontinental land connections. Some of the missing links are connected by car ferries.
One of the major components of the proposal is to span the Bering Sea with a bridge or tunnel called the Intercontinental Peace Bridge, the TKM-World Link or the AmerAsian Peace Tunnel. This would link the Cape Prince of Wales, with the Russian Cape Dezhnev. The Bering Strait Tunnel would consist of 3 tunnels connecting Alaska and Russia by going through two islands (the Little Diomede (USA) and Big Diomede (Russia)). The longest single tunnel would be 24 miles (40 km). Since the Bering Sea at the proposed crossing has a maximum known depth of 170 feet (50 m), the tunnels might be dug with conventional tunnel boring machines of the type that was employed in the construction of the Channel Tunnel. The three tunnel proposal is considered to be preferable over a bridge due to severe environmental conditions, especially the inescapable winter ice damage.
